All Time Famous Quotes of Lord Kelvin

Lord Kelvin Quotes

Lord Kelvin, born William Thomson in 1824, was a renowned physicist and mathematician known for his groundbreaking contributions to thermodynamics, electromagnetism, and engineering. He formulated the Kelvin scale of absolute temperature and played a pivotal role in elucidating the laws of thermodynamics, laying the groundwork for modern physics. Kelvin’s expertise extended to practical applications, including advancements in telegraphy and electrical engineering, notably with the transatlantic telegraph cable. His profound understanding of mathematical principles and their application in the physical sciences earned him widespread acclaim and influence. Knighted in 1866 and later raised to the peerage as Baron Kelvin, his legacy as one of the foremost scientific minds of his time endures, with his contributions continuing to shape our understanding of the natural world and technological progress. He passed away in 1907.

Lord Kelvin Quotes

1. “If you can not measure it, you can not improve it.”
— Lord Kelvin

2. “To measure is to know.”
— Lord Kelvin

3. “In science there is only physics; all the rest is stamp collecting.”
— Lord Kelvin

4. “There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.”
— Lord Kelvin

5. “When you can measure what you are speaking about, and express it in numbers, you know something about it.”
— Lord Kelvin

6. “Fourier is a mathematical poem.”
— Lord Kelvin

7. “If you study science deep enough and long enough, it will force you to believe in God.”
— Lord Kelvin

8. “Heavier-than-air flying machines are impossible.”
— Lord Kelvin

9. “I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind.”
— Lord Kelvin

10. “When you are face to face with a difficulty, you are up against a discovery.”
— Lord Kelvin

11. “Quaternions came from Hamilton after his really good work had been done, and though beautifully ingenious, have been an unmixed evil to those who have touched them in any way.”
— Lord Kelvin

12. “I have no satisfaction in formulas unless I feel their numerical magnitude.”
— Lord Kelvin

13. “If we can’t express what we know in the form of numbers, we really don’t know much about it.”
— Lord Kelvin

14. “Large increases in cost with questionable increases in performance can be tolerated only in race horses and fancy women.”
— Lord Kelvin

15. “Ether is the only substance we are confident of in dynamics. One thing we are sure of and that is the reality and substantiality of the luminferous ether.”
— Lord Kelvin

16. “The more thoroughly I conduct scientific research, the more I believe that science excludes atheism.”
— Lord Kelvin

17. “Can you measure it? Can you express it in figures? Can you make a model of it? If not, your theory is apt to be based more upon imagination than upon knowledge.”
— Lord Kelvin

18. “Mathematics is the only true metaphysics.”
— Lord Kelvin

19. “Do not imagine that mathematics is harsh and crabbed, and repulsive to common sense. It is merely the etherealisation of common sense.”
— Lord Kelvin

20. “You know only insofar as you can measure.”
— Lord Kelvin

21. “Let nobody be afraid of true freedom of thought. Let us be free in thought and criticism; but, with freedom, we are bound to come to the conclusion that science is not antagonistic to religion, but a help to it.”
— Lord Kelvin

22. “Fourier’s theorem is not only one of the most beautiful results of modern analysis, but it may be said to furnish an indispensable instrument in the treatment of nearly every recondite question in modern physics.”
— Lord Kelvin

23. “Although mechanical energy is indestructible, there is a universal tendency to its dissipation, which produces throughout the system a gradual augmentation and diffusion of heat, cessation of motion and exhaustion of the potential energy of the material Universe.”
— Lord Kelvin

24. “I believe that the more thoroughly science is studied, the further does it take us from anything comparable to atheism.”
— Lord Kelvin

25. “I can never satisfy myself until I can make a mechanical model of a thing. If I can make a mechanical model, I can understand it. As long as I cannot make a mechanical model all the way through I cannot understand.”
— Lord Kelvin

26. “The atheistic idea is so nonsensical that I do not see how I can put it in words.”
— Lord Kelvin

27. “Science is bound, by the everlasting vow of honour, to face fearlessly every problem which can be fairly presented to it.”
— Lord Kelvin

28. “To live among friends is the primary essential of happiness.”
— Lord Kelvin

29. “Simplification of modes of proof is not merely an indication of advance in our knowledge of a subject, but is also the surest guarantee of readiness for farther progress.”
— Lord Kelvin

30. “I have not had a moment’s peace or happiness in respect to electromagnetic theory since November 28, 1846. All this time I have been liable to fits of ether dipsomania, kept away at intervals only by rigorous abstention from thought on the subject.”
— Lord Kelvin

31. “Vortices of pure energy can exist and, if my theories are right, can compose the bodily form of an intelligent species.”
— Lord Kelvin

32. “The only census of the senses, so far as I am aware, that ever before made them more than five, was the Irishman’s reckoning of seven senses. I presume the Irishman’s seventh sense was common sense; and I believe that the possession of that virtue by my countrymen-I speak as an Irishman.”
— Lord Kelvin

33. “When you cannot measure, your knowledge is meager and unsatisfactory.”
— Lord Kelvin

34. “I have not the smallest molecule of faith in aerial navigation other than ballooning, or of the expectation of good results from any of the trials we heard of. So you will understand that I would not care to be a member of the Aeronautical Society.”
